Water: Can It Be Too Much of a Good Thing?

Posted 3 Nov 2016 by

THURSDAY, Nov. 3, 2016 – Dehydration is a familiar foe for endurance athletes, and one that will be on the minds of every participant in Sunday's New York City Marathon. But did you know that drinking too much water can be potentially fatal, particularly if not treated properly? And you don't have to be an elite athlete like a marathoner to fall victim to what doctors call water intoxication. Water intoxication occurs when a person has consumed so much water that the salt levels in the blood become diluted, said Dr. Aaron Baggish, co-medical director of the Boston Marathon. "When sodium [salt] concentrations are low in the blood, it actually allows water to leak out of the blood into the other tissues," a condition known as hyponatremia, added Baggish, who's also associate director of the Cardiovascular Performance Program at the Massachusetts General Hospital Heart Center. The brain ... Read more

Americans Getting Adequate Water Daily, CDC Finds

Posted 26 Apr 2016 by

TUESDAY, April 26, 2016 – Americans' worries about not being properly hydrated may be unfounded: A new government report finds most are getting enough water each day. The data, from the U.S. National Health Nutrition Examination Survey for 2009 to 2012, found that adult men take in 117 ounces of water daily, on average – more than 14 cups. For women, the number is 93 ounces, or almost 12 cups daily. The study was conducted by Asher Rosinger and Kirsten Herrick, of the U.S. Centers for Disease Control and Prevention. They noted that in 2004, the Institute of Medicine set "adequate" daily intake of water at 125 ounces for men and 91 ounces for women. The new data suggest that the average man approaches the needed level, and the average woman more than meets it. Of course, not all of that fluid comes in the form of plain water. Only about 30 percent of daily water intake for men in the ... Read more

For 'Ironman' Athletes, Study Shows Danger of Too Much Water

Posted 10 Mar 2016 by

WEDNESDAY, March 9, 2016 – Long-distance triathletes who drink too much water during competition may end up with dangerously low blood sodium levels, new research warns. Researchers in Germany who tested nearly 1,100 competitors in the annual Ironman European Championships found more than 10 percent had developed this condition – called hyponatremia. In its most severe form, hyponatremia can be life-threatening, experts say. "Hyponatremia among athletes is not a new issue," said study co-author Dr. Stefan Braunecker, of the department of anesthesiology and intensive care medicine at University Hospital of Cologne. But the 2015 death of an athlete who developed hyponatremia during an Ironman competition underscores the "still urgent importance of the topic," he added. The condition occurs in a "considerable percentage" of long-distance triathletes, Braunecker and his colleagues said in ... Read more

Endurance Athletes Should Only Drink When Thirsty, Experts Say

Posted 30 Jun 2015 by

TUESDAY, June 30, 2015 – Endurance athletes or those who are very physically active should drink plenty of water – but only when they feel thirsty, new expert recommendations say. Athletes should listen to their body and drink water as needed to prevent a potentially deadly condition called exercise-associated hyponatremia (EAH) or "water intoxication." The new guidelines were developed at the International Exercise-Associated Hyponatremia Consensus Development Conference in Carlsbad, Calif., and published June 29 in the Clinical Journal of Sport Medicine. Overdrinking, particularly when exercising or playing sports in the heat, can increase the risk of seriously low levels of sodium in the blood. Excessive intake of water, sports drinks or other fluids can exceed the body's ability to get rid of fluids in sweat or urine. When the body can't remove excess fluids, those fluids dilute ...

FDA Medwatch Alert: Samsca (Tolvaptan): Drug Safety Communication - FDA Limits Duration and Usage Due To Possible Liver Injury Leading to Organ Transplant or Death

Posted 30 Apr 2013 by

ISSUE: FDA has determined that the drug Samsca (tolvaptan) should not be used for longer than 30 days and should not be used in patients with underlying liver disease because it can cause liver injury, potentially leading to liver transplant or death. FDA has worked with the manufacturer to revise the Samsca drug label to include new limitations. BACKGROUND: Samsca is a selective vasopression V2-receptor antagonist indicated for the treatment of clinically significant hypervolemic and euvolemic hyponatremia, including patients with heart failure and Syndrome of Inappropriate Antidiuretic Hormone (SIADH). An increased risk of liver injury was observed in recent large clinical trials evaluating Samsca for a new use in patients with autosomal dominant polycystic kidney disease (ADPKD). RECOMMENDATION: Samsca treatment should be stopped if the patient develops signs of liver ... Read more
